[sane-devel] Scanbd fails to start with multiple scanners (and no paper loaded)

Wed May 20 14:49:53 UTC 2015

Hello,

I’m running scanbd on a debian machine with version 1.0.25 of the sane-backend.  I installed scanbd using apt-get, sane-backend was compiled from a git clone.  I’m using two fujitsu fi-7160 scanners in my setup.  The problem: If there is no paper loaded in at least one scanner, scanbd.service will exit the main process and abort.  This failure will at a variety of times depending on the circumstances.  It will happen during startup of the machine.  It will also happen after a few minutes after a scan process is complete.  This post-scan behavior is not 100% replicable.

The following is /var/log/syslog after a system restart.  : (I can provide a more detailed log if that will be helpful)

May 20 09:40:13 hp6300pro-23 systemd[1]: Unit scanbd.service entered failed state.

It may be worth noting that there was no paper loaded in the scanners when this log file was created.  Also, after the service exits, the scanners can both be found using scanimage –L.

Currently I’ve found a work around : If a piece of paper is kept loaded in the scanners, the process starts properly after boot and seems to stay active.  Should my use case work with scanbd?  Does anyone know of a better work around?  Perhaps there is an option or setting that I have overlooked?  Thank you for any help with this issue.

Thanks,
